It seems like I have seen some Arduino footprints somewhere, just can't remember where right now? I'll do some looking around tomorrow and see if I can remember where I saw them. I'll post what I find tomorrow if anything turns up.
I saw that on JLCPCB about the assembly of the PCBs, also said starting at $7 I believe. That would be a pretty good price I think. I struggle with the SMT components as well, but I will keep practicing as I have some more here to work on.
